摘要

The determination of the strong coupling constant α _s (m_Z) from H1 inclusive and dijet cross section data [ 1 ] exploits perturbative QCD predictions in next-to-next-to-leading order (NNLO) [ 2 – 4 ]. An implementation error in the NNLO predictions was found [ 4 ] which changes the numerical values of the predictions and the resulting values of the fits. Using the corrected NNLO predictions together with inclusive jet and dijet data, the strong coupling constant is determined to be α _s (m_Z) =0.1166 (19)_exp (24)_th . Complementarily, α _s (m_Z) is determined together with parton distribution functions of the proton (PDFs) from jet and inclusive DIS data measured by the H1 experiment. The value α _s (m_Z) =0.1147 (25)_tot obtained is consistent with the determination from jet data alone. Corrected figures and numerical results are provided and the discussion is adapted accordingly.
